From left to right with the ECU plug pointing at me: G (UB), LY (UFIX), YR (US), GND (YL).

Disconnect air flow meter connector, and measure resistance between Us and GND of air flow meter... Approx 70 Ohm when flap is fully closed Between Ub and GND: Approx 300 Ohm Ufix and GND: Approx 200 Ohm Us and GND (With flap opened fully): Approx 50 OHM (With flap closed fully): 500 Ohm Looks to be identical to the EA82 MAF.

From the EA81T wiring diagram supplement, May 1983: 1) Set key in switch in IG position. (Engine off) 2) Measure voltage between check connector II air flow meter Ufix (LY) + and ground (BR) - 3) Apporx 5V? I'll continue when you reply because its like 3 pages long and I have no scanner.

:slobber: Must... fix.... coupe.....wagon..... Nice job on the enigne!

I just got the new downpipe on and this thing sounds like a beast! Moving on to the clutch next!

Don't need to hit the mountains to find snow anymore!!! 10 inches at my casa, and not a subaru in sight...

Yes and they work awesome!!! I've got a set and I'm VERY pleased with them so far.

AMEN!!! I'm shocked that that it took five posts to get the truth out. A lightened flywheel will: NOT reduce torque NOT change the torque curve for the worse (WILL look better) make it easier to stall make your clutch easier to overheat (You are lightening your heat sink) NOT change your gearing NOT make it harder to accelerate up hill

So what was the spread between new and old gen cars? I really wanted to go but was worried about not seeing any old school cars. My guess is that the two RXs were about it... Maybe a couple brats and other EA series but not enough to warrent a visit.

I'll check tomorrow when I'm around my car. Have you checked the FSM?

What kind of garrett are you using?

I'll tell you right now, they're not even close.

Sounds like what I did. You can get a brass drift at any decent tool store or probably Sears.

I was gonna say that I couldn't tell the difference, but you beat me to it Zap!

Maybe I'll find the right place this year if I can get any of my 'rus back on the road. EDIT: I'm out, sorry guys...

I have a bent inner tie rod on a EA81T power steering rack. I also have a good manual rack from a carb'd EA81. Are the inner tie rods from these two application interchangable? Does anyone have the part numbers for the two parts?

Heres what I got from my Power Mechanics class a couple years ago regarding camshaft drive systems: Cogged belts are light, strong, durable, but you would be lucky to breach 100k miles with them. Chain driven systems are stronger than belts and more durable, but are heavy and can stretch, plus they wear out tensioners. Gear driven systems can handle high speeds (F1), they are accurate and can have very tight packaging but are heavy, expensive and noisy compared to the other systems. It all depends on your application. FHI could have used a chain or even gears on the EA82 engine, but it was simpler and more cost effective to use belts. One advertising slogan during the 80's was "Inexpensive and built to stay that way" and this was one of those things they did to ensure that.

Thats what I ended up doing, and it worked. Now to do the same to my EA71! WooHoo!!

I would buy a west coast car if I were you.... Who knows what other evil lurks under that poor, tired, rusted out car...

Well the claw hammer method was a bust for me. I guess I'll try to borrow a slide hammer from Schucks or something.

Not to hijak the thread, but I have the capability to port heads and manifolds if anyone is interested for their projects. I'll have pics soon and numbers for my work before the end of the quarter hopefully. Oh and clutch wise, Clutchnet.com used to list all the old subarus, but they are hard to get a hold of and their new page doesn't list our cars anymore.

Yeah, the stock carb'd EA81 pistons are like 8.7:1 or something while the stock turbo ones are 7.7:1.

I don't even have my VF11 in yet!! I got the SS header on, then ran into the problem of not having an o2 sensor port. That is being solved with a 3" DP, but I have to work to get that in, and thats just to get it running on the stock turbo. From there I'll turn up the boost a little and work on getting my WRX IC in there. Once all that is done I can look at the VF11 and then MegaSquirt 'n' Spark. I'll keep everyone updated in a seperate thread once meaninful progress is made. Current Mods: BoostedBalls SS header MSD Blaster 3 coil custom 2.5" exhaust w/ Flowmaster muffler K&N stock panel filter in cut airbox EA82 5 speed swap Lots of gauges

I'll give that one a try. Thank you SOOOO much!!

Is it possible to remove EA81 wrist pins without a slide hammer? I don't have one, but need to get them out.
